FASTENING FOR-MEETlNG-RAlLS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 316,219, dated Apri121,1885.

Application filed January 21, 1885. (No model.)

To all whom it may concern:

Be it known that I, GEORGE M. BAKER, a

citizen of the United States, residing at New Britain, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Sash-Fasteners, of which the following is aspecification.

In the accompanying drawings, Figure 1 is a plan view of mysash-fastener. Fig. 2 is a side elevation of the same. Fig. 3 isa frontelevation thereof. Fig. 4 is a sectional View, partly in elevation, online 00 x of Fig. 1, but with the keeper-cam turned around nearly intothe position indicated by the broken lines in said figure; and Fig. 5 isa plan view of one part of my sash-fastener, with the knocking-out camomitted.

A designates the hooked latch, pivoted by means of the pintle a to thelugs bb of the base-plate'A. The bulk of its weight is at the rear ofitspivot, and when turned back its heel strikes the base-plate A, as shownin Fig. 4, so as to hold the latch by its own weight in nearly avertical position. hen this latch is turned forward for engagement withthe companion part of the fastener, it passes the balancing-point justprior to engagement therewith.

B designates a side acting cam,which serves as a keeper for the hookedlatch. This cam is pivoted to thekeeper-plate B so as to swinghorizontally thereon. In addition to its upwardly-projecting inclinedflange c, which forms the cam proper, it is provided with a knocking-outcam, d. It is also provided with an operatinghaudle, C. Its movementupon the base-plate may be limited by means of any suitable stopsas, forinstance, the pin Fig. 1, on the keeper-plate and the ends of the curvedsloth in the body of the keepercam, or vice versa.

When the keeper-cam is in the position illustrated in Fig. 4, the latchA may be pushed forward over the edge of the inclined flange c at thefoot ofits incline, as indicated by broken lines in Fig. 4. The handle 0is then forced around toward the left, so that the keepercam pulls uponthe hooked latch, thereby forcing the lower sash downward and the uppersash upward, bringing them home in case they were not fully closed, andthen as the strain upon the latch is exerted obliquely (see Fig. 2) itpulls the sash-rails firmly together, making a firm lock, which cannotbe picked. Upon the return movement of the keeper-cam to unlock thefastener theknockingout cam (1 will strike the hooked-end of the latchjust before said keeper-cam reaches the stop, as indicated by brokenlines in Fig. 1, and thereby throw the latch back out of engagement farenough to have its own weight carry and hold it back, as illustrated infull lines in Fig. 4.

The sash-fastener shown in Fig. 5 is substantially the same as thatshown in the other figures, except that the knocking-out cam is omittedand the stop is slightly different. In this fastener the weight of thehook will throw it back so soon as said hook is released by the backwardmovement of the inclined flange c. The flange c is also longer than inthe other figures, so that it will force the sashes up and down to agreater extent.

I claim as my invention 1. In a sash-fastener, in combination with arotatable side acting cam, a hooked latch or keeper adapted to engagesaid cam, said hooked keeper being so pivoted in its supporting-platethat it may be swung laterally out of engagement with the cam when notin use, substantially as herein described, and for the purpose setforth.

2. The combination of the hooked latch, the side acting keeper-camhaving the inclined flange for engagement with the hooked end of thelatch, and the knocking-out cam, all substantially as described, and forthe purpose specified.

GEORGE M. BAKER.
